20. Coin-Toss Simulator

Write a class named Coin. The Coin class should have the following field: A String named sideUp. The sideUp field will hold either heads or tails indicating

the side of the coin that is facing up. The Coin class should have the following methods:

A no-arg constructor that calls the toss method, described next.

A void method named toss that simulates the tossing of the coin. When the tossmethod is called, it generates a random number in the range of 0 through 1. If the random number is 0, then it sets the sideUp field to heads. If the random number

is 1, then it sets the sideUp field to tails.

A method named getSideUp that returns the value of the sideUp field.

Write a program that demonstrates the Coin class. The program should create an instance of the class and display the side that is initially facing up. Then, use a loop to toss the coin 20 times. Each time the coin is tossed, display the side that is facing up. The program should keep count of the number of times a head is facing up and the number of times a tail is facing up and display those values after the loop finishes.
